A 5.20 mol 5.20 mol sample of solid A A was placed in a sealed 1.00 L container and allowed to decompose into gaseous B B and C

. C. The concentration of B B steadily increased until it reached 1.10 M, 1.10 M, where it remained constant. A ( s ) − ⇀ ↽ − B ( g ) + C ( g ) A(s)↽−−⇀B(g)+C(g) Then, the container volume was doubled and equilibrium was re‑established. How many moles of A A remain?

Water flows through a horizontal pipe (from a wider area to narrow area section) and then out into the atmosphere at a speed v1
Darina [25.2K]

Answer:

V = 6.36 m³

Explanation:

For this exercise we will use fluid mechanics relations, starting with the continuity equation.

Let's write the flow equation

        Q = v₁ A₁

       

The area of ​​a circle is

        A = π r²

Radius is half the diameter

        A = π/4  d²

        Q = v₁ π/4 d₁²

        Q = π/ 4 15 0.03 2

        Q = 0.0106 m3 / s

The volume of water in t = 10 min = 10 60 = 600 s

        Q = V / t

        V = Q t

         V = 0.0106 600

          V = 6.36 m³

What is the IMA of a two-gear system if the resistance gear has 54 teeth and the effort
Dafna1 [17]

Answer:

IMA = 2

Explanation:

Given the following data;

Resistance gear = 54 teeth

Effort gear = 23 teeth

To find the ideal mechanical advantage (IMA);

IMA = number of teeth on the resistance gear/number of teeth on the effort gear

Substituting into the equation, we have;

IMA = 54/23

IMA = 2.35 ≈ 2

Therefore, the ideal mechanical advantage (IMA) of this two-gear system is 2.

A wire carrying a 30.0-A current passes between the poles of a strong magnet that is perpendicular to its field and experiences
Zanzabum

Answer:

1.79 T

Explanation:

Applying,

F = BILsin∅................ Equation 1

Where F = Force, B = magnetic field, I = current flowing through the wire, L = length of the wire, ∅ = angle between the magntic field and the force

make B the subject of the equation

B = F/ILsin∅............. Equation 2

From the question,

Given: F = 2.15 N, I = 30 A, L = 4.00 cm = 0.04 m, ∅ = 90° (perpendicular to the field)

Substitute these values into equation 2

B = 2.15/(30×0.04×sin90°)

B = 2.15/1.2

B = 1.79 T

Hence the average field strength is 1.79 T
